Haha…..and the award for creative Q. of the day goes to @rojo !
I’d go for maximum splatter power, the fan at about a 45 degree angle when the shit hits it.
Of course the density of the shit would determine it’s splatter pattern.
I think a medium soft shit such as cat or dog poo would be the best consistency, goose poo is too liquid and horse shit is too dry, bunny and goat poo is pelleted so only a small percentage would actually be ground up through the fan blades.

YES!! Mythbusters did it.PLAUSIBLE
To begin, Adam and Jamie decided to create imitation poop that would be more hygienic and pleasant to work with. Jamie came up with a formula that had the similar physical properties (density, compressibility, and stickiness) to real dog poop. Adam built a slingshot to throw the poop at the fan at roughly 30 mph.

The first tests used a 12-inch fan with plastic blades. Without any impressive results, they quickly upgraded to a 20-inch fan with metal blades and formulated the imitation poop to be softer. Still not achieving 360° splatter, they upgraded to a 30-inch fan with a ¼ horsepower motor, which created enough splatter to call this idiom plausible. As a finale, Adam and Jamie used a very large box fan and all of their leftover fake poop to create a giant mess.
